To all t may concern.' v

'Be it .known that I, ALBERT E. Coon, of

' the city. of Odebolt, Sac county, lState of Iowa, have invented certain new and useful Improvements y in Motor-Flows, 'of which the following isa full, clear, and exact speelfication, such as will .enable others skilled in -the art'to which it appertainsto Imaire and use the same.

VMy invention relates to certain 4improvegmentsin motor plows of that class in 'which plow, to simplify devices for steering the plow,

ends.

a frame is sustained' by the cultivating or plowing tools and in which a motor mounted on the frame is positively geared vor otherwise connected wlth a part or a' whole of such tools so thatthey act not only to 4cultivate the earth7 but to `propel the apparatus.

The object .of my present invention is lto improve the organization k.of this type of its elements and to render it more durable :md eiiicient in operation.

A further object is to so organize the parts that the frame may lie low with respect to the cultivating tools',l thus lowering .the apparatus as awhole and increasing its stability.

Still a further object is to improve zthe devices for mounting the frame on the cultivating tools so that the plow may adapt itself to unevenness in the ground with perfeet ease of motion. l Still a further object is to improve the avoiding and exthereby the necessity of frequent combined cultivtensive adjustment of the vating and propelling tools.

I attain these and various other objects, briefly, by providing a frame on which an engine or motor is mounted intermediate its Real-ward of the motor are arranged a number of gangs of combined propelling and cultivating tools. These are preferably in the form of rotary disks and each gang is carried on a tool frame which framesare arranged to swing or turn around vertical axeson auxiliary frames which are spring 'mounted above the main frame. These tools are connected by suitable gearing with the engine and preferably rearward of said propelling and cultivating tools is arranged a gearing in connection with the tool frames so that the inclination of the tool frames to the line of travel of the plow may be varied at will. At the forward portion of the mainA frame I arrange an auxiliary one of the amecarries a fifth wheel device in which i a wheel lis arranged. This wheel serves the purpose of steerrng the a paratus and supporting the front end of t e machine and it 1s connected b a peculiar mechanismvwith a steering whee at the rear o f the plow. Cultivatin; disksmay be arranged at the front end ofgthe plow if desired.- but this ris not essential. A e e,

invention involves various other features of importance and'all will-be full set forth hereinafter and particularly pointed ont in the claims.

Reference /is had to the accompanying drawings, which one manner in which the varioufelements of my invention may be embodied, in which drawings,

Figure 1 is a plan view of the appara-tus showing the parts in detail as fully as the iliary frame, andthe particular gearin 'for transmitting the driving motion to sait tools. Fig. 3 is a side elevation of the com'- plete apparatus as shown in Fig. l; Fig. L is an enlarged sectional view on the line 4-4 of Fig. 6, through the axial shaftof gangs of vcultivating and propelling tools, particularly illustrating the man ner in which they are mounted to 'rotate'on the tool frames Fig. 5 is an enlarged sectional View showing thesteering gear and the gearing for adjusting the inclination of the gangs of propelling and cultivating tools to the line of travel of the plow. Flg. 6 is an enlar ed plan View of one gang of tools and its too frame, this view also showing the sheave over which the cable runs for adjusting the gang of tools. Fig. 7 is a cross section on the line 7-7 of Fig. 6 showing the manner in which the tool frames are mounted to turn on the auxiliary frames; Fig. 8 is a detail section on the line 8 8 of Fig. 1 showing the manner in which the auxiliary frames are spring-mounted 'on the main frame. Fig. 9 is a side elevation with parts in Section on the line 9-9 of Fig. l0 showing t-he fifth wheel device at the front of the "machine with'the means for springk mountillustrate as an example,

ing it on the main frame and indicating the i p transverse connectin front gang of disks; and Fig. 1() is a fragmentary plan view of these parts.

The main frame is, by preference, constructed rectangular in forni and composed of side members each comprising opposed channel irons 15 rigidly secured to each other but slightly spaced apart as inl dicated in Figs. 1 and 2. The side members of the frame are connected by transverse members, the specific arrangement of which is not important, but which,` according to the construction shown in the drawings. are indicated at 16, 17, 18, 19, 20 and 21. rlhese members are located two adjacent to the ront end, two approximately at the middle of the frame and two adjacent to the rear end. The engine or motor which may be of any desired form, is indicated in outline at 22 and is bedded on the cross members 18 and 19. The front cross members 20 and 21 carry the front steering wheel or roller and the rear cross members 16 and 17 carry a seat and tool chest 23 together with the steering and adjusting gear which will hereinafter fully appear. y

I will now describe the construction and organization of the gangs of combined cultivating and propellmg tools which are arranged at the rear portion of the frame be hind the engine 22. As shown best in Fig. 1, there are four gangs of these tools or disks, two gangs arranged at each side of the machine. These tools are indicated at 24. As shown best in Figs. 2 and 4, the rotating disks or cultivating tools of each gang are fastened on axial shafts 25 and interposed between said parts are thimbles 26 which` hold the parts 24 and 25 rigid with each other. The tool frames have main or upper portions 27 from which arms 28 project downward. These arms are` laterally curved so that they may reach in between the concave-convex disks without interference therewith and terminate at their lower ends in boxes 29. Suitable bearing bushings or the like indicatedv at 30, are interposed between the boxes and thimbles vto insure free rotation of the disks, axial shaft and thimbles.

Referring now to Figs. 2 and 7, the upper or main part 27 of the tool frames are provided with vertical boxes 31 and in these are received the 'downwardly extending studs 32 of cross members 34 on the auxiliary frames. 35 indicates a king bolt extending from the auxiliary frame through the stud 32 and engaging a disk or washer 36 on the underside of the box 31 of the tool. frame.

In this manner the tool frames are mounted to turn around vertical axes, and are sustained on the auxiliary frames. jThe tool frames are also provided with large sheaves 37 (see Figs. 1, 2, 6 and 7) which are arranged at the level of the upper portions 27 of the tool frames and are adapted to have chains or cables 38 passed around them to adjust the inclination of the gangs of tools as will fully appear heremafter.

As shown best in Figs. 1, 2, 3, 7, and 8, there are two auxiliary frames at the rear portion of the apparatus which frames are each composed, in addition to the cross members 34 before described (see Figs. 1, 2, and A I 7), of an intermediate cross member 39 and two side members 40, the side members extending longitudinal of the auxiliary frames and transversely of the apparatus. These frames are located above themain frame and, as shown best in Figs. 2 and 8, are con` nected thereto by means ofblocks 41 which are fastened between the channel irons 15 of the side members of the main frame. From these blocks 41 stout bolts or pins 42 rise. These pins or bolts 42 extend loosely through openings in the central cross members 39 of the auxiliary frames which members are heavily constructed, with openings for the pins 42 sufficiently large to allow perfect ease of movement. Above and below the cross members 39 disks or washers 43 bear and at the upper ends of the pins are located nuts 44. Stout expansive springs 45 bear between the blocks 41 and lower washers 43 and similar springs 46 bear between the nuts 44 and upper washers 43.`

In this manner the auxiliary frames are spring sustained above and on the main frame and are allowed a wide freedom of movement thereon. At the same time a thorough spring mounting of the frame is effected which makes the apparatus very l much easier in operation and prevents racking and jarring the partssupported on the main frame.

From the engine 22 a gear 47 of any suitable sort drives a rotary shaft 48 which is revolubly mounted at its ends in boxes 49 secured to the side members of the main frame.- This shaft 48 carries respectively at its end portions, sprockets 50 over which chains 51 pass respectively to differential l gears 52. There are two differential gears l provided, one for each of the two gangs of cultivating tools at the sides of the machine. Said differential gears may be of the usual .or any desired construction and connected 1 with shaft sections 53 rotatably mounted in suitable bearings on the auxiliary frames. The shaft sections 53 are each connected by universal joints 54 and 55 with shaft sections 56 mounted in boxes 57 attached to the upper port-ions 27 of the tool frames. The

universal joints 54 and 55 are so arranged i that the universal connection effected by them is vertically coincident with the centers around which the tool frames` turn on the auxiliary frames, sc ,that the motion of the tool frames on the auxiliary frames will not interfere with transmision on the shafts imanes? 53 and 56, the .shafts 56 swinging with the tool frames. Said shafts 56 carry sprockets 58 and these are connected by chains 59 with sprockets'60 rsecured to one of the thimbles 26 of the disk gangs. From this arrangement it follows that the shaft-48 driven from the engine, drives the'differential gears 52 and these gears drive the shaft sections 53 which in turn, through the universal joints 54-55, drive the shaft sections 56, which last 'shaft sections are geared with the respective gangs of disks. The gangs of disks are thus rotated from the engine irrespective of the adjustment of the tool frames around the vertical axis. The engine, of course, 'or the gearing driven therefrom, may fbe provided at any convenient point with a clutch and speed change gear to vary and control the speed at which the disks are driven. The differential gears 52 serve vto compensate for the differential motio of the two connected-disk angs which di erential'motion will be incident to the movement of the disk gangs in arcs of different radii.

Referring to. Fig. 1, it will be seen that of the two pairs of disk gangs, the gangs of each pair are disposed at an angle to each other and 'the left hand and right hand gangs of each pair are in parallelism. To maintain this relative arrangement, the chains or cables 38 ofthe parallel gangs are cross connected to'two drums 61 in the manner shown 'in fFig. 1 so that when these drum's are rotated,-equivalent motions will be imparted to-each of the parallel gangs,

maintaining their characteristic relation.-

These two drums 61 andthe devices for operating them, are best shown in Figs. 1, 3, and 5. Referring particularly to Fig. 5, the shafts of the drums 61 are mounted 1n boxes 62attached in any suitable manner to the cross member 17 of the main frame, and carry worm wheels 63, one located above its drum and -the other below its drum, and both meshed respectively 'with worms 64 fastened to shafts 65 also at different elevations. The shafts 65 lare rotatably mounted y in suitable bearings and carry beveled gears 66 in mesh with bevel gears 67 and68 secured respectively to a hollow shaft 69 and a solid shaft 70. The hollow shaft 69 receives a second hollow shaft 71 and the hollow shaft 71 in turn receives the solid shaft 70. Boxes 72 and 73 are provided to sustain the inner shafts and said boxes 'are suitably mounted on the frame in any de-l sired manner. The solid shaft pro-jects below the hollow shaft 71 and the hollow shaft-71 projects below the shaft 69 and box 72. At its lower extremity, the hollow shaft 71 carries a worm 74 which meshes with a. worm wheel 75 disposedin a vertical plane and fastened on a horizontal shaft 76 mounted in boxes 77 sustained in any yieldingly sustained below suitable manner on the main frame of the machine. At its ends, .the shaft 76 carries drums 78 which` are connected with 'the steering cables las will hereinafter fully appear. These shafts 69, 70 and 71 extend `vertically in front of the seat 22 and lre-l spectively carry hand Wheels 78, 79 and. 80. by which they may be independentlygrotated. With respect, therefore, to the mechanism forradjusting the inclination of the combined cultivating and propelling disks,

it will be seen that this may be manuallv 83 which frise from it and pass loosely' through vertical openings in the main frame. The bolts 83 are provided with nuts 84 at their upper ends and, encircling theA bolts above and below the main frame, are springs 85 substantially similar to the springs 46 which t-hus spring-mount the main frame on the auxiliary frame 81. The braces -82 of the auxiliary frarne 81 carry guide rollers 86 having vertical axes and the main portions of the auxiliary frame 81 carry pairs of guide rollers 87 having horizontal axes. iBetween these horizontal and vertical guide 4rollers 86 and 87 is arranged a fifth wheel or annulus 88 which as shown best in Fig. 9, is T-shaped in section and lies horizontally. This` annulus carries depending arms 89 in which is held the axial shaft 90 of the front wheel 91. 'It will thus be seen that the fifth wheel or annulus 88, with its connected wheel .91, may be turned around a vertical axis and that the fifth wheel is snugly guided in all directions by means of the rollers 86 and 87. It willalso beseen that this fifthv wheel, supported in the auxiliary frame 81, is the main frame, thus allowing perfect freedomy of motion in all directions. Depending from the fifth wheel or annulus 88 are a number of brackets 92 which carry a sheave 9 3. This sheave encircles the wheel 91 and has a chain or cable 94 turned around it, the ends of which chain or cab-le extend rearward and are turned around the drums 78 in opposite directions so that by operation of the hand wheel 80, thetr'ain of the gearing connecting the same with the drums 78 is operated and the drums 78, pulling and slacking on the ends of the cable 94, adjust the inclination of the wheel 91. This whee .91 in addition to supporting the front o i' the apparatus serves also as asteering means; By

ysa4

turning the hand wheel 80, the plow may be moved in any desired direction.

The operation of the apparatus will, it is believed be enerally understood fr, the foregoing. he parts being assembled as shown, and the o eration of the engine started, rotation o the rear gangof cultivating and' pro elling tools will canse` said tools to enter t e earth and plow the same. At the same time, these tools, actingA on crossing lines, en a e the earth witha vpropelling eiect an t e resultant ofthe oposing forces sends the plow straightahead.

he p owing action of t e disks may be regulated by re ulating the inclination of their `gangs to eac other, causing the disks togenr the ground-to a greater or less extent, and to low with a narrowl or'wider furrow as esired. The, direction or course of the apparatus is-controlled by the ad'ustment of the wheel 91 throu h theme ium of thehand wheel 80 and-'1s connections. lThe operator, resting on the, seat 23, con-,v

trols the 'entire operation of thel apparat-us. The-apparatus may also be provi ed with seeding or planting devices and various other attachments so that it ma be made to serve byu-one operation, to per orm a.- num;

ber of operations heretofore'performed loA separate ap aratus. In addition to this,-xit may be ma e to carry at its rear, li rrow teeth for harrowing the lsoil and lor. (Shing the clods, thus increasing its field of usefulness materially.

It will be observed from the drawings that the members of both pairs of gangs of disks engage their convex faces with each other so that the thrust is balanced between the members of the pairs of disks. The disks in operating have an end thrust owing to the form ofthe disks and to their inclina- -tion to the line of travel and ordinarily would tend to buckle the gangof disks, z'. e. causing one end. to sink more deeply into the earth than the other. By engaging the gangs with each other as explained, the thrust is balanced and counteraoted and the disks are caused to work evenly in the earth.' Further, the strain on the pivotal connections between the teethzand auxiliary frames is relieved and it isvmade `possible to shift and turn the disks more rapidly. In vthis connection it will be seen that the axle or shaft which. mounts the disks is countersunk in the flange to which the end disk is fastened so that the convex side of therein, a stud pin rising from the main Laviana .frame and passing through the opening,

springs surrounding the stud pin above and below `the auxiliary frame and disks res ectively mounted on the end portions of t e auxiliary frame.
